LOCOMOTIVE-BOILER.

SPECIFICATION forming part of Letters Patent N o. 706,490, dated August 5, 1902.

Application filed March 7, 1902. Serial No. 97,110. (No model.) l l.

To all whom t may 0071/061177,.-

Beit known that I, JOSEPH J. GAGE, a citizen of the United States, residing at Mansiield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Locomotive-Boilers, of which the following is a specification.

My invention relates to improvements in locomotive-boilers; and the obj ects of my invention are, first, to provide a means to lengthen the durability of boileriiues in locomotives; second, to prevent a certain amount of vibration to the lues when the engine is in motion, obviating to a great extent the lines from becoming loose in the flue-sheet next to the fire-box. These objects I accomplish by the mechanism illustrated in the accompanying drawings, in which- Figure l is a longitudinal sectional view of a locomotive-boiler embodyingrny invention;

Fig. 2 is a transverse sectional view enlarged, taken in line no a, Fig. 1, showing the construction of the inner flue-sheet. Fig. 3 is a longitudinal sectional view of one of the iiues, also a portion of the inner and outer fine-sheets, enlarged to show more fully the construction and arrangementof the parts constituting my invention.

Similar letters of reference indicate the several parts throughoutthe several views.

In the accompanying drawings, Aindicates a locomotive-boiler which is of the44 class now in general use; B and O, theiiue-sheets or heads in which are secured lthe endsof the lues. The flue-sheetB indicates the head of the boiler next to the fire-box and forms the back wall of the same. f

In the place of only using a front and rear end flue-sheet I place in the front of fluesheet B a third, (indicatedA by the letter D.) This flue-sheet is hanged around its outer periphery and is secured in asuitable manner within the boiler about two and one-half feet in front of the sheet B. The object of the said head or ilus-sheet is to shorten thelength of bearings by forming a support for the iiues E between the two end flue-sheets. By placing the sheet Din the position as shown in Fig. A1 it preventsvthe iiues from springing from their-normal line when the locomotive is in motion. The openings VF in the luesheet D are sufficiently large to admit a copper sleeve G, which surroundstheilues The said sleeve isswagedupon each side of the flue-sheet D, holding the flues firmly in position. Placed withinthe interior of the flues E are short iluesII. They are sufficiently large in theirouter diameter to iill the interior diameter oftheiiues. These iiues extend from the fire-box a sufficient distance to pass through the flue-'sheet D,.the outer yends expanded and swagedover the ends of the flues E. Thelobjectsof the said inner iues are to strengthen the flues next to the fire-box, and by swaging the same over the ends of main flues protects the ends from coming in contact with the fire and preventing them from turning and becoming loose, which is of-common occurrence in all locomotive-boilers. 5- v The inner fine is fullyshown in Fig. 3. Between each of the openings for the flues in the flue-sheet D` are perforations J and also an opening K above the line of flues. The perforations and opening are to allow a free passage for` the water and steam. Having fully described my invention, what I claim as new, and desire to secure by Letters Patent,"isl 4 In a device of the typeset forth, the combination withaboiler having front and rear heads, of an intermediate vertical head secured in front of the rear head, with a series of horizontal flues passing through all of said heads, the intermediate headsupporting the weightof the flues between the front and rearheads, a series of short flues located within saidfirst-named flues and extending from JOSEPH J. GAGE.
